Semen Quality In White Leghorn Chicken Selected For Egg Production Traits, Shanmugam Murugesan, Niranjan Matam, Rakesh Kulkarni, Tarun Kumar Bhattacharya, Rudranath Chatterjee
Turkish Journal of Veterinary & Animal Sciences
The present study was conducted to evaluate the effect of selection for egg production traits in White Leghorn chicken based upon the semen quality. Males of 3 pure lines of White Leghorn, namely IWH, IWI, and IWK, along with a pedigree random-bred control (IWC) population, were selected and housed in individual cages. The semen collected from individual birds was evaluated for different physical and biochemical parameters. There was significant (P =< 0.013) difference in semen quality parameters studied between the lines. High egg-producing lines IWH and IWI had poor semen quality in comparison with that of the control line (IWC). Thus, it can be concluded that selection for higher egg production affects the semen quality of males in the selected lines.

In Vitro Effects Of Melatonin On Hyaluronidase Activity And Sperm Motility In Bull Semen, Sadetti̇n Tanyildizi, Tanzer Bozkurt, Osman Çi̇ftçi̇, Fati̇h Saki̇n
Turkish Journal of Veterinary & Animal Sciences
The effects of melatonin on hyaluronidase activity of semen and spermatozoa motility of Holstein bulls were investigation in vitro. Semen samples were divided into 5 equal parts and incubated (v/v) with melatonin at the doses of 0.5, 1, 2 and 4 mM for 60 min. Percentages of spermatozoa motility, morphological abnormality and hyaluronidase activity of semen were determined at 5, 10, 15, 20, 30 and 60 min during incubation. Results show that melatonin caused a significant (P < 0.001) decrease in the spermatozoa motility, while causing a significant increase in the hyaluronidase activities of the semen. However, there was no significant difference in the percentages of abnormal spermatozoa when compared with control samples. Doses of 0.5, 1, 2 and 4 mM of melatonin in bull semen decreased the percentage of spermatozoa motility in a time- and dose-dependent manner. The mean percentages of abnormal spermatozoa were not affected by melatonin treatment. However, it caused an increased hyaluronidase activity of bull semen. In conclusion, the existence of melatonin in bull semen has a significant effect on fertilization ability by affecting spermatozoa motility and hyaluronidase activity.
